Abstract Metal mediated several organic reactions are known which can be used inside the cellular medium for protein modifications, eventually targeting diseases. Indeed, due to their ease of handling, rapid solubility, and effective cell penetration, metals superior than any other competitor as a stimulus/mediator in relevant with modifications. most chemical biology tool Cu(I)‐catalyzed azide‐alkyne cycloaddition(CuAAC)/click or Pd multiple intra/extra modifications etc. A few examples Au(III), Ru(III) also known. Among these, click reaction has high potential management biomolecules within cells, thus this methodology is adopted broadly chemistry, towards therapeutic applications pharmacology. Fast kinetics aqueous at ambient normal temperature specificity between precursors (e. g., azide alkyne bio‐orthogonal cells) essential aspects behind success metal intracellular reactions. This review dealt specifically live achievements challenges.

Abstract Photosensitizer‐assisted photocatalytic systems offer a solution to overcome the limitations of inherent light harvesting capabilities in catalysts. However, achieving efficient charge transfer between dissociative photosensitizer and catalyst poses significant challenge. Incorporating photosensitive components into reactive centers establish well‐defined channels is expected effectively address this issue. Herein, electrostatic‐driven self‐assembly method utilized integrate photosensitizers metal–organic frameworks, constructing atomically Ru‐Cu bi‐functional units promote local electron migration. Within newly constructed system, [Ru(bpy) 2 ] 2+ component Cu site serve as catalytic active for photocarrier generation H O production, respectively, their integration significantly reduces barriers transfer. Ultrafast spectroscopy situ characterization unveil accelerated directional over units, presenting orders magnitude improvement systems. As result, 37.2‐fold enhancement rate (570.9 µmol g −1 h ) that system (15.3 achieved. This work presents promising strategy integrating atomic‐scale achieve ultrafast enhanced performance.

New concepts to treat eye diseases have emerged that elegantly combine unnatural light exposure with chemical biology approaches achieve superior cellular specificity and, as a result, improvement of visual function. Historically, without further molecular treatment has offered limited success including photocoagulation halt pathological blood vessel growth or low stimulate retinal cell viability. To add such treatments, researchers introduced various biological light-sensing molecules and combined those exposure. (Pre-)clinical trials describe the use optogenetics channelrhodpsins, i. e. light-sensitive ion channels, in patient vision restoration. In arena, pharmacological agents, rendered by reversible modification photosensitive protecting compounds ("caging"), been applied eyes living mice photo-release specific activities. Among these were successful proof-of-principle experiments conducted establish photo-sensitive gene therapies eye.

Selective inhibition of TrxR1 over TrxR2 is a highly sought-after goal, because the two enzymes play distinct roles in cancer progression. However, achieving targeted challenging due to their high homology and identical active site sequence. Herein we report new subcellular photocatalysis approach for by controllably activating organogold(I) prodrugs within cytosol, exclusive location TrxR1. The NHC-Au(I)-alkynyl complexes are stable evenly distributed cell; they can meanwhile be efficiently transformed into NHC-Au(I)-L species (L = labile ligands) via radical mechanism photocatalysts released cytosol (from endosome/lysosome) upon light irradiation, leading selective without affecting TrxR2. This results strong cytotoxicity cells with much higher selectivity than auranofin, pan TrxR inhibitor that cannot discriminate TrxR1/2, along potent antitumor activities multiple zebrafish mouse models. prodrug activation may thus suggest novel precision targeting using remarkable spatial control photocatalysis.

Published: Jan. 1, 2025

Abstract Bioorthogonal chemistry has revolutionized the field of chemical biology, providing powerful tools for manipulating molecules in biological environments, including living cells and organisms. For many years, these transformations have been mainly limited to well-known copper-catalyzed azide–alkyne cycloadditions (CuAAC) metal-free reactions with strained reagents. However, recent years it widely demonstrated that some transition-metal-catalyzed may also be performed settings, enabling, among other applications, bioimaging targets structures or pro drug activations. Particularly attractive is possibility using organometallic catalysis performing synthetic, bond-forming reactions, as this can lead new types technologies exploration biomedical discovery.
